RF DATA TRANSCEIVER MODULE
XTR-7020A-8

These multi-channel
transceivers are a simple
and economical solution
for a wireless data
transmission at high data
rates. The integrated
micro-processor can be
controlled with TTL logic
RS-232 and generates the
data packets on its own.
Thereby, the user does
not have to take care of
the programming of
software routines and the
transmission management.
Via the initialization of
the internal registers
the frequency channels,
the serial data rates
(9600-19200-38400-57600-115200
bps) and the output power
(RF power from -8 to +10
dBm) can be set. It is
possible to select
different speeds for the
RS-232 signals of two
modules. By means of an
internal buffer storage
in the module, the data
can be transmitted with
data packets of max. 240
bytes packet length.
Ranges (LOS) of 300 m at
an optimum antenna
adjustment are possible.

RF DATA MODEM WIZ-7020A-8

These "stand-alone" radio
modems incl. integrated
PCB-antenna permit a
"half-duplex" operation
of digital data in the
TTL RS-232 format. It is
possible to connect the
module directly to the
interface to a UART of an
external micro-processor
or to a serial port of a
PC by means of the W 232
adapter. Its simple
handling does not require
any experience in the
HB-area. No restriction
in the size of the data
packets.

868.95 MHz Transmitter In New
SRD Band

Suitable receiver for the
handheld transmitter part
no. 19 00 50 with one
relay changeover contact.
Operation can be set to
either monostable or
bistable for remote
switching of many
products, for example,
garage or door opening,
alarm systems, lights,
roller shutters, awning,
central locks and such.
The code is set with
soldering pins. To reduce
power consumption &ndash
for instance, when
supplied by solar panels
or batteries &ndash
clocking can regulate the
power supply! Breaking
capacity of 6A/230V/AC.

SRD Transmitter Module

The frequency that the
SRD transmitter and
receiver modules use,
868.95 MHz, is in a
frequency range newly
approved for short-term
signal transfers. Through
low-use by other radio
services and the
mandatory channel
separation, a
disturbance-free signal
is guaranteed. The
modules are useful for
transferring serial data,
for example, for
setting up an alarm
system, to turn on
signals and for sending
alarm signals,
measurements and similar
from a distance of up to
100 metres.
Electromagnetic
interference fields,
structures and stray
radiation from machinery
may lessen the range. The
modules have general
approval and can be used
in the EU (with the
exception of Greece)
without registration or
payment of fees.
Connection is made over a
pin connector with a pin
spacing of 2.54 mm.

MULTICHANNEL-RADIO TRANSMITTER
CS-10 SE

The radio transmitter
CS-10 SE is for wireless
transmission of switching
signals and set in the
control-technique. Each
radio transmitter of the
CS-10 SE can be used as
transmitter and receiver,
each has 4 digital and
one analogue inputs /
outputs. Thus, 2 radio
transmitters are needed
for a transmission route.
Under optimum conditions
distances ranging up to
800 m in the open can be
covered!
The function of the
transmitter is selected
from 4 operating modes:
In the Switching mode the
current information
present is transmitted
for a duration of 1.2 s
upon each change at one
or more of the 4 digital
inputs. The receiver
converts this information
at the digital outputs in
the ratio of 01:01 um and
retains the state till it
receives another signal.
In the scan mode the
digital inputs D1 to D4
behave like the
transmission keys of a
handheld transmitter. The
information is
transmitted as long as
one or more of the 4
inputs at the transmitter
are activated. In case of
the individual pulse
counting the transmission
unit counts and stores
the pulse at the 4
digital inputs and
transmits these to the
receiver every 2 minutes.
There, the 4 separate
pulse information are
output with a
pulse/pause-ratio of 20
ms. In case of the Pulse
pair counting the 4
digital inputs of the
transmitter are put
together to 2 pulse
pairs. The number of the
pulses is counted and at
the same time their
sequence is
differentiated in this
way a direction can be
identified based on the
pulse sequence.

SRD Receiver Module

Receiver for 230 V
release circuit 19 03 20,
as well as for serial
data transfer with TX-9.
Power consumption can
bereduced through
clocking. Suggested
antenna: &lambda /4 wire
antenna (8.7 cm) or
displaced receiver
antenna for 868.95 MHz,

2-ch. Hand-held Trans. For SRD
Band

The relay in the receiver
can be turned on or off
with the two keys or be
switched into two
separate receivers with a
key function each. The
transmission mode is
displayed by an LED.
Multiple assignments are
possible, that means
several transmitter can
control one or more
receivers. The code is
set with soldering pins.
The transmission
frequency of 868.95 MHz
is in the new SRD band,
and because of the low
use through other radio
services and the channel
separation
disturbance-free signal
during use is guaranteed.
The hand-held transmitter
has general approval and
can be used in the EU
(with the exception of
Greece) and Switzerland
without registration or
payment of fees.

MULTICHANNEL-RADIO TRANSMITTER
CS-10 RB

The radio transmitter
CS-10 RB is used for a
wireless transmission of
switching signals,
pulses and measured
values in the control
technology and measured
values recording. Each
radio transmitter of the
CS-10 RB can be used as
transmitter and receiver
and each has 4 digital
and one analogue inputs /
outputs. Thus, 2 radio
transmitters are needed
for a transmission route.
Under optimum conditions
distances ranging up to
1000 m in the open can be
covered!
The function of the
transmitter is selected
from 4 operating modes:
In the Switching mode the
current information
present is transmitted
for duration of 1.2 s
upon each change at one
or more of the 4 digital
inputs. The receiver

at the digital outputs in
the ratio of 01:01 um and
retains the state till it
receives another signal.
In the scan mode the
digital inputs D1 to D4
behave like the
transmission keys of a
handheld transmitter. The
information is
transmitted as long as
one or more of the 4
inputs at the transmitter
are activated. The
voltage or the current
value of the analogue
input is thereby updated
constantly. The receiver
displays static the
analogue value received
at the output, till the
next received information
overwrites the
value.
